We report here the first three-dimensional structure of the D1 C-terminal processing protease (D1P), which is encoded by the ctpA gene. This enzyme removes the C-terminal extension of the D1 polypeptide of photosystem II of oxygenic photosynthesis. P

Publikováno v: Journal of Biological Chemistry. 272:20348-20356

Polypeptide D1 of the photosystem II reaction center of oxygenic photosynthesis is expressed in precursor form (pre-D1), and it must be proteolytically processed at its C terminus to enable assembly of the manganese cluster responsible for photosynth

Spectroscopic evidence from site-directed mutants of Synechocystis PCC6803 in favor of a close interaction between histidine 189 and redox-active tyrosine 160, both of polypeptide D2 of the photosystem II reaction center

Publikováno v: Biochemistry. 32:13742-13748

The reaction center of photosystem II of oxygenic photosynthesis contains two redox-active tyrosines called Z and D, each of which can act as an electron donor to the oxidized primary electron donor, P680+. These tyrosines are located in homologous p

The redox active tyrosines, YZ and YD, of Photosystem II are oxidized by P680+ to the neutral radical. Such oxidation requires coupling of electron transfer to the transfer of the phenolic proton. Studies of the multiphasic kinetics of YZ oxidation i

Site-directed mutations at D1-His198 and D2-His197 of photosystem II in Synechocystis PCC 6803: sites of primary charge separation and cation and triplet stabilization

Publikováno v: Biochemistry. 40(31)

Site-directed mutations were introduced to replace D1-His198 and D2-His197 of the D1 and D2 polypeptides, respectively, of the photosystem II (PSII) reaction center of Synechocystis PCC 6803. These residues coordinate chlorophylls P(A) and P(B) which

Engineering and Rapid Purification of Histidine-Tagged Photosystem II from Synechocystis PCC 6803

Autor: Michael J. Reifler, Bruce A. Diner, Jamie Wang, Gary W. Brudvig, Dexter A. Chisholm

Publikováno v: Photosynthesis: Mechanisms and Effects ISBN: 9780792355472

The cyanobacterium Synechocystis PCC 6803 is especially useful in site-directed mutagenesis studies of photosystem II (PSII). Unfortunately, methods which rely on ion-exchange chromatography for recovery of the mutant PSII (1–4) are lengthy and can
